51. The Gaia-PS1-SDSS (GPS1) Proper Motion Catalog
ID:

Title:
The Gaia-PS1-SDSS (GPS1) Proper Motion Catalog
Short Name:
GPS1
Date:

Publisher:

Description:
This catalog combines Gaia DR1, Pan-STARRS 1, SDSS and 2MASS astrometry to compute proper motions for 350 million sources across three-fourths of the sky down to a magnitude of mr≈20. Positions of galaxies from Pan-STARRS 1 are used to build a reference frame for PS1, SDSS, and 2MASS data. Gaia DR1 is adapted to that reference frame by exploiting that locally, proper motions are linear. GPS1 has a characteristic systematic error of less than 0.3 mas/yr, and a typical precision of 1.5−2.0 mas/yr. The proper motions have been validated using galaxies, open clusters, distant giant stars and QSOs. In comparison with other published faint proper motion catalogs, GPS1's systematic error (<0.3 mas/yr) is about 10 times better than that of PPMXL and UCAC4 (>2.0 mas/yr). Similarly, its precision (~1.5 mas/yr) is an improvement by ∼ 4 times relative to PPMXL and UCAC4 (∼6.0 mas/yr). For QSOs, the precision of GPS1 is found to be worse (∼2.0−3.0 mas/yr), possibly due to their particular differential chromatic refraction (DCR).

Description:
This is the Henry Draper catalog (HD, Cannon & Pickering 1918-1924) as distributed by the Astronomical Data Center in 1989 (Vizier III/135A), with Gaia DR2 source_ids and positions added. The link to modern Gaia DR2 was done through Fabricius et al's match between HD and Tycho 2 (Vizier IV/25), TGAS to match Tycho 2 and Gaia DR1, and Gaia DR2 to match against Gaia DR1.
53. The HSOY Catalog

Title:
The HSOY Catalog
Short Name:
HSOY SCS
Date:

Publisher:
The GAVO DC team
Description:
HSOY is a catalog of 583'001'653 objects with precise astrometry based on PPMXL and Gaia DR1. Typical formal errors at mean epoch in proper motion are below 1 mas/yr for objects brighter than 10 mag, and about 5 mas/yr at the faint end (about 20 mag). South of -30 degrees, astrometry is significantly worse. HSOY also contains, where available, USNO-B, Gaia, and 2MASS photometry. HSOY's positions and proper motions are given for epoch J2000. The catalog becomes severely incomplete faintwards of 16 mag in the G-band. The mean epochs are typically very close to Gaia's J2015. HSOY still contains about 0.7% spurious close "binaries" (non-matched stars) from the original USNO-B (marked with non-NULL clone). Also, failed matches within Gaia DR1 contribute another 1.5% spurious pairs (marked with non-NULL comp). In both cases, astrometry presumably is sub-standard.

Description:
A catalogue of 541 nearby (within 10pc of the sun) stars, brown dwarfs, and confirmed exoplanets in 336 systems, as well 21 candidates, compiled from SIMBAD and several other sources. Where available, astrometry and photometry from Gaia eDR3 has been inserted.
55. The PPMXL Catalog

Title:
The PPMXL Catalog
Short Name:
GAVO PPMXL

Publisher:
The GAVO DC team
Description:
PPMXL is a catalog of positions, proper motions, 2MASS- and optical photometry of 900 million stars and galaxies, aiming to be complete down to about V=20 full-sky. It is the result of a re-reduction of USNO-B1 together with 2MASS to the ICRS as represented by PPMX. This service additionally provides improved proper motions computed according to Vickers et al, 2016 (:bibcode:`2016AJ....151...99V`).

Publisher:

Description:
Parts I and III of the sixth fundamental catalog, a catalog of high-precision astrometry for bright stars combining centuries of ground-based observations as reflected in FK5 with HIPPARCOS astrometry. The result contains, in particular for the proper motions, statistically significant improvements of the Hipparcos data und represents a system of unprecedented accuracy for these 4150 fundamental stars. The typical mean error in pm is 0.35 mas/year for 878 basic stars, and 0.59 mas/year for the sample of the 3272 additional stars.
